A case report of free forearm dermal flap reconstruction in a patient with tongue cancer and psoriasis vulgaris

Dermal flap reconstruction in the oral cavity in a patient complicated with psoriasis vulgaris has not been described yet. Here, we report the case of a 33-year-old man with untreated psoriasis vulgaris who was diagnosed with right tongue SCC (T4aN0M0). Surgery is our preferred approach in such cases, and flap reconstruction was deemed necessary after resection. Because of psoriasis vulgaris, the donor site exhibited erythema, rash, and scaling. Surgery comprising forearm dermal flap reconstruction following palliation of cutis symptoms was performed. Currently, 2 years after surgery, there have been no symptoms of psoriasis vulgaris in the oral cavity and no tumor recurrence.
